| 摘 要： | 通过对锦屏一级水电站普斯罗沟坝址左岸深部裂缝空间发育规律、深部裂缝变形特征的考察 ,从地质、力学、数值方法多方面分析了造成深部裂缝发育规律和变形特征的因素。在此基础上明确指出 ,普斯罗沟左岸深部裂缝的成因就是边坡在自重应力和构造应力的复合应力场卸荷的结果 ,没有超出常规意义下边坡卸荷作用的范畴。

| Abstract: | s:The paper comprehensively studies distribution of the fractures as well as their deformation features, and then analyses the factors influencing their distribution and deformation feature by geology,mechanics as well as numerical simulation.Thereafter,the paper concludes that deep fractures were the result of release of high geostatic stress including body stress and tectonic stress. |
